RedRock® RR112-1G42-531/532 & RR112-1G43-531/532 TMR Analog Magnetic Sensor

The RedRock® RR112-1G42-531/532 and RR112-1G43-531/532 are analog magnetic sensors with proportional linear voltage output ideal for use in medical, industrial, automotive, and consumer applications. Based on patented Tunneling Magnetoresistance (TMR) technology with seamless CMOS integration, the RR112 offers multiple configurations of several parameters to enable applications such as proximity sensing, rotary sensing, and level detection.  Short lead times are making RedRock® TMR Magnetic Sensors a popular replacement alternative for hard-to-get Hall Effect Sensors and Reed Switches

The RR112 series features a magnetic field range from -80 to +80 G (-8 mT to +8 mT) with a typical sensitivity of 5mV/V/G (50 mV/V/mT). It is rated to operate across a wide temperature range of -40°C up to 125°C. It offers a wide supply voltage range from 1.7 up to 5.5 V, ideal for applications ranging from small battery-powered electronics to industrial machinery.  (See Datasheet)
